FARM MACHINERY 



INSTRUCTIONS TO STUDENTS. 

The f ii'st exercises and in fact the largest part of those 
in the book are to get the student familiar with the dif- 
ferent parts of the machine, the principal differences in 
the various makes of the same type of machine and the 
function of each part. For these exercises thei'e are 
questions asked, the ansv/er to which the student must de- 
termine and jot down aside of the question. Blank spaces 
are left for these notations, or, if no blank space is left, 
the part of the question not applying to the machine can 
be crossed out. Sufficient machines of the same kind 
should be gone over to fill out all of the report sheets for 
that machine. After the report blanks for one kind of 
machine, such as walking plows or mowers, etc., are filled 
out, then the student should present himself to the in- 
structor for a quiz on that machine. A grade will then 
be given. 

In the case of assembling and testing exercises the stu- 
dent does the exercise as per instructions in the manual 
and additional instructions from the instructor. All re- 
sults should be carefully tabulated in manual. 

Each student will need a manual and a pocket tapt?. 
As soon as getting the manual the student should writo 
his name on it in ink thus insuring its retui'n in case of 
loss. Not more than three students should work together 
if all are to get the maximum benefit of the course. 

In using the machinery and apparatus in the labor- 
atory, take care of it as well as you would if it were your 
own. Keep in mind that, while the machinery is loaned 
to us and the apparatus belongs to the State, yet there 
are many other students coming after you and they too 
wish to have good machinery and apparatus to use. 

Do not rush through your laboratory work or do not 
loaf. Work right along making each moment count for 
the most. Get all you can out of the laboratory work. 
Do not run to the instructor with every little question, but 
try to rely upon yourself. Remember that the laboratory 
work is built on the assumption that you have the class 
room work in good shape; if you fail there, you are lost 
here.

LABORATORY MANUAL 



BINDER ATTACHMENT ADJUSTMENT. 
Instructions. Exercise No. 41. 

Adjust binder attachment on grain binder so it will 
tie small tight bundles. Tie ten bundles in order to be 
sure that it will not miss. Readjust so it will tie large 
tight bundles. Tie ten bundles with it adjusted this way. 
When finished fill in report at bottom of page. 

The following instructions will be of assistance in 
making the adjustments and if anything should go wrong 
they will assist in finding just what the trouble is. 

In adjustment of the springs for tension it would be 
well to turn the nut only M turn at a time until the 
proper tension is obained. 

Cord holder or twine disc spring. This should grip 
the twine tight enough that there is only a slight slippage 
of the twine in the disc when knotter revolves. If too 
tight, twine is broken. If too loose, twine will slip out 
from the disc. 

Knotter spring. If too tight, twine wll be broken 
when knot is tied. If too loose, the knot will not be tied 
tight and may come undone when the bundle is handled. 

Bundle sizer spring. This is the spring whose ten- 
sion must be overcome to throw binder into gear for tieing 
a bundle. It regulates the tightness of packing, and 
to some extent the size of bundle. If band is loose on 
bundle this spring is probably too loose. Do not attempt 
to remedy a loose band by making twine tension very 
tight. 

Twine tension. This should be only tight enough to 
keep the slack out of the twine. It is not used to make 
the machine tie tight bundles. 

Knife. The knife should be snug up against the 
twine at the instant the knotter closes so the next move- 
ment will cut the twine and strip the twine from the 
knotter. If it is attached by a malleable arm, the arm 
may be bent. Knife must be sharp. 

Needle. The needle is of malleable iron, and some- 
times gets sprung up so that it does not deposit the twine 
in the twine disc. It should clear the twine disc by *A 
inch and pass over far enough to make sure of placing

GRAIN DRILL CALIBRATION. 



Instructions. 



Exercise No. 44. 



Calibrate a grain drill with two different kinds of 
seed, make two tests with each seed, sowing dif- 
ferent amounts each time. 

Measure width of di'ill and circumference of wheel 
in feet. Determine the number of x'evolutions 
that wheel must turn in oi'der to plant an acre. 

Get from instructor sufficient clean seed to over 
half fill seed box. He will also tell you the 
amounts to sow per acre. Set the drill to sow 
one of these amounts. Put under each spout a 
separate vessel, such as a paper sack, to catch the 
seed. Turn wheel until seed is running in good 
shape from each spout. Then empty each sack 
back in seed box. Then start calibration — turn 
wheel number of revolutions to plant one-half 
acre. Be careful to tui-n wheel at about same 
speed as it will run in field.
